UBIc photometry of ACO2390 early-type galaxies

We investigate a spectroscopic sample of 48 early-type galaxies in the rich cluster Abell 2390 at z=0.23 and 48 early-type galaxies from a previously published survey of Abell...本研究针对红移z=0.23的富星系团阿贝尔2390（Abell 2390）中的48个早型星系的光谱样本，以及来自此前已发表的阿贝尔相关巡天调查中的48个早型星系展开研究。
